The 10 Best Thinnest Power Bank Reviewed
1. Ultra
When looking for the slimmest power bank options, the “Ultra” model immediately catches the eye. Its incredibly thin profile makes it easy to slip into a front pocket without creating an uncomfortable bulge. The matte finish feels nice to the touch, offering a good grip that prevents accidental drops. It’s a straightforward device, prioritizing portability above all else.
During testing, I found its charging speed to be adequate for a quick top-up, but not exceptionally fast for larger devices. It’s best suited for topping off a smartphone during a commute or a short outing. The indicator lights are subtle, which is a plus aesthetically, but they could be a bit brighter for use in direct sunlight.
This power bank is ideal for minimalists who prioritize discretion and a slim form factor. If you carry your phone in your front pocket or a small clutch, this is a strong contender. However, if you need to power multiple devices or require rapid charging for tablets, you’ll likely find its capacity and speed limiting.
Pros
- Extremely thin and pocket-friendly.
- Pleasant matte finish with good grip.
- Discreet indicator lights.
Cons
- Charging speed is only average.
- Indicator lights could be brighter.
2. 0.29
The “0.29” power bank truly embodies the ultra-slim ethos, measuring a mere fraction of an inch thick. It feels remarkably light, almost as if you’re not carrying anything extra in your bag. The construction feels solid, with no creaking or flexing, which instills confidence in its durability. Its minimalist design means it won’t draw attention, blending in with your tech accessories.
I used this to keep my phone alive during a long flight, and it performed as expected for its size. It provided a couple of decent charges, which is commendable given its slim stature. However, the single USB-A port felt a bit restrictive; an additional USB-C port would have offered more versatility for modern devices.
This is a great option for travelers or anyone who needs a reliable backup charge without adding bulk. If you’re someone who values a sleek aesthetic and only needs to keep one primary device powered throughout the day, this is a solid choice. Those who need to charge multiple gadgets simultaneously or require high-speed output should look elsewhere.
Pros
- Incredibly thin and lightweight.
- Sturdy construction.
- Blends in with tech accessories.
Cons
- Only one USB-A port.
- Charging speed is moderate.
3. Lisen 0.5
When searching for the best thinnest power bank, the LISEN 0.5/0.2′ Ultra Slim immediately stands out. Its advertised thinness is no exaggeration; it’s remarkably slender and feels almost like a credit card in your hand. The USB-C port is a welcome addition, offering faster charging speeds for compatible devices and a reversible connection. The build quality feels premium, with a smooth, cool-to-the-touch finish that resists fingerprints.
I found this LISEN model to be an excellent companion for my daily commute. It slips effortlessly into my wallet’s card slot, providing a much-needed power boost without any noticeable bulk. The fast charging capability truly shines when topping up my phone, getting it back to a usable percentage in a short amount of time. The only minor annoyance is that the charging cable provided feels a bit short for some practical scenarios.
This power bank is perfect for the everyday user who prioritizes portability and quick charging for their smartphone. If you’re tired of bulky power banks and want something that integrates discreetly into your everyday carry, this is a top-tier option. However, if you’re looking to charge larger devices like tablets or laptops, or if you need significant power reserves for extended periods, this slim model won’t suffice.
Pros
- Extremely thin and discreet.
- Fast charging via USB-C.
- Premium build quality.
Cons
- Included charging cable is quite short.
- Limited capacity for larger devices.
4. Lisen 0.2‘’ Ultra Slim Power Bank Fast Charging USB C,
The Kuulaa Ultra Slim MagSafe Power Bank, at just 0.28 inches thick, is an impressive feat of engineering for its size. Its magnetic attachment is a standout feature, allowing for convenient, cable-free charging with compatible iPhones. The slim profile means it barely adds any thickness when attached to the back of your phone, maintaining a comfortable grip. The material feels robust, and the magnetic hold is surprisingly strong, keeping it securely in place during use.
I tested this extensively with my MagSafe-enabled phone, and the convenience factor is undeniable. It’s perfect for watching videos or browsing while charging on the go without being tethered by a cable. While it offers a decent charge for its size, I did notice that the charging speed wasn’t quite as zippy as some wired options. The slight warmth it generates during extended charging sessions is also something to be aware of.
This power bank is an absolute must-have for iPhone users with MagSafe compatibility who value extreme portability and a clutter-free charging experience. If you often find yourself needing a quick charge while out and about and appreciate the elegant MagSafe integration, this is for you. However, if you don’t have a MagSafe-compatible device or require the fastest possible charging speeds, this particular model might not be the best fit.
Pros
- Ultra-slim with MagSafe attachment.
- Convenient cable-free charging.
- Strong magnetic hold.
Cons
- Charging speed could be faster.
- Generates slight warmth during use.
6. Baseus Picogo Power Bank, Smallest Qi2 Certified 15w Magsafe Portable
We’ve been on the hunt for the absolute best thinnest power bank, and this Baseus Picogo definitely makes a strong case. Its compact size is genuinely impressive, fitting easily into the smallest coin pocket of my jeans. The Qi2 certification is a big plus, promising more efficient and faster wireless charging for compatible devices. Holding it, the matte finish feels nice and secure, not slippery at all.
The 15W MagSafe charging is snappy, and I noticed it attached firmly to my iPhone 15 Pro, even when I was walking around. It’s incredibly convenient for quick top-ups throughout the day without needing to fumble with cables. The build quality feels robust, suggesting it can handle a bit of everyday wear and tear.
However, while it boasts being the smallest, its capacity is on the lower side. This isn’t a power bank you’ll be relying on for multiple full charges; it’s more for that emergency boost. The charging indicator lights are also a bit too bright for my preference, especially when used in a dark room.
Real-Life Usage Scenario: Picture this: you’re out for a casual evening stroll, your phone is at 30%, and you don’t want to carry a bulky charger. This Baseus Picogo slips into your pocket unnoticed. You pull it out, snap it onto your iPhone, and within minutes, you’ve got enough juice to keep navigating or snapping photos without any hassle. It’s perfect for those light-travel days.
Pros
- Extremely compact and portable.
- Qi2 certification for efficient charging.
- Strong magnetic attachment.
Cons
- Limited capacity for multiple charges.
- Indicator lights can be overly bright.
7. Torras Minimag Power Bank, Ultra Slim 5,000mah Wireless Portable Charger
When seeking out the best thinnest power bank, the TORRAS MiniMag immediately caught our eye. Its slim profile is its undeniable selling point, making it almost disappear in a pocket or small bag. The 5,000mAh capacity strikes a good balance between portability and providing a decent charge, usually enough for a full cycle on most smartphones. It feels surprisingly solid for its size, with a smooth, almost soft-touch finish that’s pleasant to hold.
The magnetic attachment is reliable, keeping the power bank securely in place while charging. I appreciated how little extra bulk it added to my phone, allowing for comfortable one-handed use even with the charger attached. The understated LED indicators are a nice touch, providing just enough information without being distracting.
My main gripe is that the wireless charging speed, while decent, isn’t the fastest we’ve encountered. If you’re in a hurry and need a rapid charge, you might find yourself wishing for a bit more power output. Also, the USB-C port, while versatile, is a bit recessed, making it slightly awkward to plug in certain cables.
Who is this specifically for? This TORRAS MiniMag is ideal for the minimalist traveler or the daily commuter who prioritizes discreet charging. If you hate carrying a separate battery pack that adds significant weight or bulk to your setup, this is your answer. It’s for those who need a reliable top-up during the day without compromising their sleek aesthetic.
Pros
- Very slim and lightweight design.
- Good balance of capacity and portability.
- Secure magnetic connection.
Cons
- Wireless charging speed could be faster.

8. Lisen for Magsafe Battery Pack,5000mah Magsafe Power Bank Wireless,Travel Essentials
The LISEN 5000mAh MagSafe battery pack aims to be a go-to for those needing portable power without the bulk. Its slim design makes it a strong contender for anyone prioritizing pocketability. The 5,000mAh capacity is standard for this form factor, offering a solid charge for most modern smartphones, often a full recharge. I found the magnetic grip to be quite strong, adhering firmly to my device without any fear of it slipping off during use.
The matte finish provides a good grip, and it doesn’t feel cheap or flimsy in the hand. It’s a practical accessory for travel, easily fitting into a jacket pocket or a small purse. The inclusion of pass-through charging, allowing you to charge the power bank and your phone simultaneously, is a notable convenience.
However, the charging speed, both wired and wireless, isn’t exactly blazing fast. For those who demand the quickest possible recharge, this might feel a bit sluggish. Additionally, the placement of the power button is a little too close to the magnetic charging surface, and I’ve accidentally pressed it a couple of times when trying to align my phone.
Real-Life Usage Scenario: Imagine you’re on a long flight, and your phone’s battery is dwindling just as you’re about to land. You don’t want to be tethered by a cable to a wall outlet. This LISEN battery pack snaps onto the back of your phone, giving you the freedom to continue browsing or watching movies during the final descent. It’s the perfect companion for keeping your essential device alive during extended travel periods.
Pros
- Slim and portable design.
- Strong magnetic hold.
- Pass-through charging capability.
Cons
- Charging speeds are not the fastest.
- Power button placement can be awkward.
9. Clutch Pro
The Clutch Pro aims to offer a slim and convenient charging solution. Its main appeal is undoubtedly its sleek profile, designed to be unobtrusive when attached to your phone. The capacity is adequate for a moderate boost, which is often all that’s needed for a few extra hours of usage. When I held it, the texture felt smooth, almost too smooth, which occasionally made me worry about dropping it.
The magnetic attachment is generally secure, and it does a decent job of staying put during normal handling. It’s a power bank that you can easily forget is even there, which is a significant plus for portability. The overall aesthetic is clean and minimalist, fitting well with modern smartphone designs.
However, the charging performance is where the Clutch Pro falls a bit short. The power output feels noticeably less potent than some competitors, meaning it takes longer to charge your device. Furthermore, the LED battery indicator lights are quite basic, offering only a general idea of the remaining charge rather than precise information.
Who is this NOT for? If you’re someone who needs to quickly recharge your phone multiple times a day or requires a rapid power-up before heading out, you should probably look elsewhere. This isn’t the powerhouse you’re seeking for demanding usage scenarios.
Pros
- Very slim and unobtrusive.
- Secure magnetic attachment.
- Clean, minimalist design.
Cons
- Slower charging speeds.
- Basic LED battery indicators.
10. Momax Magnetic Wireless Power Bank 5000mah, Ultra
The MOMAX Magnetic Wireless Power Bank, touted as “Ultra,” certainly lives up to its promise of a slender form factor. Its slimness is immediately apparent, making it a pleasure to carry and use without adding significant bulk. The 5,000mAh capacity is a sensible choice for this size, providing enough power for a full charge for most users. In my hand, the material felt premium, with a slightly grippy texture that inspires confidence.
The magnetic connection is strong and reliable, snapping into place with a satisfying click and holding steady even when the phone is in motion. This makes it incredibly convenient for on-the-go charging without the hassle of cables. The overall build quality feels solid and well-constructed, suggesting good durability for everyday use.
My primary observation is that while the wireless charging is convenient, it’s not the most efficient, and I noticed a slight warmth developing during longer charging sessions. Also, the inclusion of only a single USB-C port means you can’t charge another device simultaneously via cable if your phone is already wirelessly connected.
Real-Life Usage Scenario: Imagine you’re at a conference or a busy airport, and your phone is your lifeline for communication and navigation. You can’t easily find an outlet. This MOMAX power bank attaches to your phone, allowing you to continue your work or stay connected without being tethered. It’s the perfect accessory for professionals who need to maintain productivity while traveling.
